ail'v relates to the construct-ion of the gearshifting lever and the casing in which it is in closed when used in that ty e of transmission mechanism styled sliding gear.

The object of the present invention is to provide` ii construction which will readily permit the removal of the gear-shifting lever without, as a preliminary operation, dismounting any other part of the transmission mechanism, and the invention consists in :1 novel construction of casing and a novel construction of gear-shifting lever, and general arrangement of the parts whereby the above specified object of the invention may be put into practice, the accompanying drawings showing the invention as embodied in its )referred form.

Referring to these drawings, a indicates the casing 'of a transmission mechanism of the type specified: b a portion of that shaft .2

and c and u'vtwo of such gears connected tofeiiier bv a collar e (or the gears and collar iiiav be integral) groovedto receive the two ends of a forked lever 1' which is the gear- .shifiing lever. and whereby these gears c and d ina v` he moved towards either end of the jgear c whereupon it may TRANSmSSION-GE AR.

ing, said shaft being positioned at right,

angles to the shaft b, to the end that theosciiiation of the shaft h will swing the lever 7' lengthwise of the shaft b and thus shift the gears c and d in the manner specified.

To secure the lever j' to the shaft h the end of the latteris made triangular in cross sec-v tion and a siiriilarly shaped hole is made, iny the hub g of the lever f, said hub preferably being split longitudinally, as at 'm-,j and after 65 being fitted to the end of the shaft is secured thereon by means of a bolt o passed through the split hub portion.- Any other means of securing the hub to the shaft may beadopted if desired.

The ends of the forked lever f are provided with rolls p, as usual in constructions of this character, which rolls fit the grooved collar e.

lt will be observed that the forked art of f rlever f, as viewed in Fig. 2, is of circular form, and of greater diameter than that of the gear c, and it will be observed also that over the end of thel shaft zto which the shifting lever is secured is an o ening rin the casing, closed b v a cap s. shaft Ii extending through the casing, an arm t is secured which, by suitable connections not shown, is actuated to swing the shifting lever in the manner described.

n that end of the To remove the gear-shifting lever f with- 35 l screw the nut on the bolt o, or similar fastenmg, and the shaft 7i may then be driven outA of its hearing thus releasing the lever By introducing the hand in the han( hole zin the. top of the casing, (a part thereof only being shown in the drawings) the l'i-erfniay be grasped and drawn towards the hand-hole until the largest diameter of the forked end of the lever is in position to )ass it over the e turned and swung up flat towards the top of the casing, 100

What we claim, is:- l. In a sliding gear transmission mechang, sliding gears mounted therein,

- a gear-sliding,r lever liaviug forked arms, the

spread of'which is greater than the diameter 11u of one of the sliding gears, there being an openinrf-hrough the' casing incloslng the 'gears t ough which said lever may be dismounted 4from its bearing, whereby it ma. 5 be passed over one ofthe 4gears with whim it engages to remove it from the casing.

whereby the lever may be passed over said geur und remove-d from its operative position, there being an opening in the casing ing said mechanism, through which said 15 i. lever may be passed.
